Description

Technical Field

[0001] This utility model relates to the field of hoisting, and in particular to a drainage cylinder hoisting tool. Background Technology

[0002] In some subsea discharge projects, pipelines are typically laid from land to the sea for discharge. However, for projects with large discharge volumes, the method of excavating subsea tunnels as drainage tunnels has emerged. These tunnels connect to the ocean via risers that penetrate the seabed. A drainage cylinder is placed at the top of the riser as an end cap and outlet. Both the riser and the drainage cylinder can be made of concrete. Their large size and weight place high demands on the offshore hoisting of the drainage cylinder and its connection and installation with the riser. It is crucial to avoid collisions that could damage the riser during hoisting and installation of the drainage cylinder, and to prevent the hoisting ropes from scraping against the concrete structure of the drainage cylinder, causing it to collapse. Furthermore, the hoisting equipment must be able to quickly disengage from the drainage cylinder at sea. Therefore, a special hoisting tool is needed to handle the hoisting of concrete drainage cylinders. Utility Model Content

[0003] The purpose of this utility model is to provide a drainage cylinder lifting tool to address the problems existing in the prior art regarding the hoisting of drainage cylinders in concrete structures, such as the need to prevent the hoisting rope from scraping against the drainage cylinder and causing it to collapse, and the need for the lifting tool and the drainage cylinder to be able to quickly disengage at sea.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A drainage cylinder lifting device includes a cross-shaped hanger and pre-embedded lifting pins; the cross-shaped hanger includes four cantilever ends, and the bottom of each cantilever end is provided with a lower lifting lug; the pre-embedded lifting pins are pre-embedded and connected to the side wall of the drainage cylinder, and the pre-embedded lifting pins include four pins evenly arranged along the circumference of the drainage cylinder, the outer end of each pre-embedded lifting pin extends out of the outer wall of the drainage cylinder to form a lifting section, the lifting section and the lower lifting lug are connected by a lower lifting rope, the lower lifting rope is configured to be vertical, and the lower lifting rope is hooked onto the lifting section.

[0005] The drainage cylinder lifting device described in this utility model uses a cross-shaped lifting frame and a lower lifting lug to extend the lower lifting rope. The lower lifting rope can be vertically connected to the lifting section, ensuring that the lower lifting rope does not contact the outer wall of the drainage cylinder during lifting, thus preventing scratching the concrete structure and causing collapse. Simultaneously, a pre-embedded lifting pin is embedded and, as part of the drainage cylinder, is not retrieved. The lower lifting rope can be hooked onto the lifting section with the pre-embedded lifting pin. After the drainage cylinder is lifted into place, divers can directly remove the lower lifting rope from the lifting section, retrieving only the lower lifting rope. The lower lifting rope and the lifting section can be quickly disconnected, reducing the difficulty of underwater operations. This drainage cylinder lifting device has a simple structure, is easy to use, and has good performance.

[0006] As a preferred technical solution of this utility model, the top of the cantilever end is provided with an upper lifting lug, the position of which corresponds to the position of the lower lifting lug.

[0007] As a further preferred technical solution of this utility model, the upper lifting lug is connected to the crane via an upper lifting rope.

[0008] As a further preferred technical solution of this utility model, the cross-shaped hanger includes a first segment and a second segment. The first segment is cross-shaped, and the end of the first segment is connected to the second segment. The upper hanger and the lower hanger are located at the end of the second segment.

[0009] As a further preferred technical solution of this utility model, both the first segment and the second segment are made of rectangular steel pipes. The first segment is welded into a cross shape by the rectangular steel pipes. The first segment and the second segment are connected by a flange. The upper lifting lug and the lower lifting lug are both welded to the second segment.

[0010] As a further preferred technical solution of this utility model, several stiffening plates are welded to the intersection of the first segment.

[0011] As a further preferred technical solution of this utility model, adjacent second segments are connected by a diagonal connecting rod, and both ends of the diagonal connecting rod are hinged to the corresponding second segment.

[0012] As a preferred technical solution of this utility model, the part of the pre-embedded hanging pin shaft embedded in the side wall of the drainage cylinder is a pre-embedded section. The two ends of the pre-embedded section are respectively provided with a first baffle and a second baffle. The first baffle is fitted into the inner wall of the drainage cylinder, and the second baffle is fitted into the outer wall of the drainage cylinder.

[0013] As a preferred technical solution of this utility model, the end of the hoisting section is provided with an anti-detachment plate.

[0014] As a preferred technical solution of this utility model, the diameter of the hoisting section gradually increases from the middle to both ends.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: This utility model discloses a drainage cylinder lifting device. The lower lifting rope is extended via a cross-shaped lifting bracket and a lower lifting lug. The lower lifting rope can be vertically connected to the lifting section, ensuring that it does not contact the outer wall of the drainage cylinder during lifting, preventing scratches on the concrete structure and potential collapse. Simultaneously, a pre-embedded lifting pin is embedded and not retrieved as part of the drainage cylinder. The lower lifting rope can be hooked onto the lifting section with the pre-embedded lifting pin. After the drainage cylinder is lifted into place, divers can directly remove the lower lifting rope from the lifting section, retrieving only the lower lifting rope. The lower lifting rope and the lifting section can be quickly disconnected, reducing the difficulty of underwater operations. This drainage cylinder lifting device has a simple structure, is easy to use, and has good performance. Attached Figure Description

Detailed Implementation

[0018] The present invention will be further described in detail below with reference to experimental examples and specific embodiments. However, this should not be construed as limiting the scope of the above-mentioned subject matter of the present invention to the following embodiments. All technologies implemented based on the content of the present invention fall within the scope of the present invention.

[0019] Unless otherwise specified, the use of terms such as "upper," "lower," "left," "right," "center," "inner," and "outer" to indicate orientation or positional relationships in the description of specific embodiments of this utility model is based on the orientation or positional relationships shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product / equipment / device is typically placed during use. These terms are merely for the purpose of facilitating the description of the utility model solution or simplifying the description in specific embodiments, enabling those skilled in the art to quickly understand the solution, and do not indicate or imply that a specific device / component / element must have a specific orientation, or be constructed and operated in a specific positional relationship. Therefore, they should not be construed as limitations on this utility model.

[0020] Furthermore, the use of terms such as "horizontal," "vertical," "suspended," and "parallel" does not imply that the corresponding device / component / element must be absolutely horizontal, vertical, suspended, or parallel, but rather that it can be slightly tilted or have a deviation. For example, "horizontal" merely means that its direction is more horizontal relative to "vertical," not that the structure must be completely horizontal, but can be slightly tilted. Alternatively, it can be simplified to mean that the corresponding device / component / element, when set in a "horizontal," "vertical," "suspended," or "parallel" direction, can have an error / deviation of ±10% relative to the corresponding direction, more preferably within ±8%, more preferably within ±6%, more preferably within ±5%, and more preferably within ±4%. As long as the corresponding device / component / element is within the error / deviation range, it can still achieve its function in the present invention.

[0021] Furthermore, the use of terms such as "first," "second," and "third" in terminology is merely for distinguishing descriptions of identical or similar components and should not be interpreted as emphasizing or implying the relative importance of a particular component.

[0022] Furthermore, in the description of the embodiments of this utility model, "several", "multiple", and "several" represent at least two. The number can be any number, such as two, three, four, five, six, seven, eight, or nine, and can even exceed nine.

[0023] Furthermore, in the description of the technical solution of this utility model, unless otherwise explicitly specified / limited / restricted, the terms "set up," "install," "connect," "link," "equipped with," "laid out," and "arranged" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to common connection methods in the art, such as welding, riveting, bolting, and threaded connections. Such connections can be mechanical, electrical, or communication connections; they can be direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components.

[0024] In related technologies, the hoisting of drainage cylinders in concrete structures requires avoiding the hoisting ropes from rubbing against the drainage cylinder and causing it to collapse, and also requires that the hoisting equipment and the drainage cylinder be able to be quickly disengaged at sea. Therefore, the technical solution of this application was developed, which is described below in conjunction with... Figures 1 to 5 To elaborate.

[0025] Example 1 like Figures 1 to 5 As shown, the drainage cylinder hanger of this utility model includes a cross hanger 1 and a pre-embedded hanger pin shaft 7.

[0026] like Figures 1 to 3 As shown, the cross-shaped hanger 1 includes four cantilever ends. The top of each cantilever end is provided with an upper hanging lug 2, and the bottom of each cantilever end is provided with a lower hanging lug 3. The positions of the upper hanging lug 2 and the lower hanging lug 3 correspond to each other.

[0027] In an optional embodiment, the cross-shaped hanger 1 includes a first segment 11 and a second segment 12. The first segment 11 is cross-shaped, and the end of the first segment 11 is connected to the second segment 12. The upper lifting lug 2 and the lower lifting lug 3 are located at the end of the second segment 12. Both the first segment 11 and the second segment 12 are made of rectangular steel pipes. The first segment 11 is welded into a cross shape by the rectangular steel pipes. Several stiffening plates 4 are welded to the intersection of the first segment 11. The first segment 11 and the second segment 12 are connected by a flange 13. The upper lifting lug 2 and the lower lifting lug 3 are both welded to the second segment 12. With this structural arrangement, since the size of the drainage cylinder 01 is relatively large, the size of the cross-shaped hanger 1 that matches it is correspondingly large. By connecting the segments, it is convenient to process, manufacture, transport, and install the cross-shaped hanger 1.

[0028] like Figures 1 to 3 As shown, adjacent second segments 12 are connected by diagonal connecting rods 5, and both ends of the diagonal connecting rods 5 are hinged to the corresponding second segments 12. With this structure, the diagonal connecting rods 5 connect each second segment 12 into a whole, avoiding large deformation of each cantilever end of the cross hanger 1.

[0029] like Figure 1 and Figure 2As shown, the bottom of the cross-shaped lifting frame 1 is connected to several support legs 6; in an optional embodiment, the ends of adjacent diagonal connecting rods 5 correspond to the same position of the second segment 12, and the bottom of the second segment 12 at that position is connected to one of the support legs 6. Then, another support leg 6 is also connected to the bottom of the intersection position of the first segment 11, for a total of five support legs 6, so that the cross-shaped lifting frame 1 can be placed stably on the ground at the lifting site, protecting the lower lifting lug 3 from touching the ground and facilitating the connection between the lower lifting lug 3 and the lower lifting rope 31.

[0030] like Figure 5 As shown, the pre-embedded hanging pin shaft 7 is pre-embedded and connected to the side wall of the drainage cylinder 01. The pre-embedded hanging pin shaft 7 includes four shafts and is evenly arranged along the circumference of the drainage cylinder 01. In one specific implementation, such as Figure 4 As shown, the pre-embedded hanging pin shaft 7 includes a pre-embedded section 72 and a lifting section 74. The pre-embedded section 72 is embedded in the side wall of the drainage cylinder 01, and the lifting section 74 extends out of the outer wall of the drainage cylinder 01. Preferably, in order to increase the pull-out resistance of the pre-embedded hanging pin shaft 7, a first baffle 71 and a second baffle 73 are respectively provided at both ends of the pre-embedded section 72. The first baffle 71 is fitted into the inner wall of the drainage cylinder 01, and the second baffle 73 is fitted into the outer wall of the drainage cylinder 01.

[0031] In one specific implementation, such as Figure 4 and Figure 5 As shown, the end of the lifting section 74 is provided with an anti-detachment plate 75. The lifting section 74 and the lower lifting lug 3 are connected by the lower lifting rope 31. The lower lifting rope 31 is configured to be vertical and is hooked onto the lifting section 74. The anti-detachment plate 75 prevents the hooked lower lifting rope 31 from falling off the lifting section 74. Preferably, the diameter of the lifting section 74 gradually increases from the middle to both ends. The middle position of the lifting section 74 corresponds to the lifting hole position of the lower lifting lug 3. When the crane connects to the upper lifting lug 2 through the upper lifting rope 21 and lifts the drainage cylinder, the lower lifting rope 31 gradually straightens. One end of the lower lifting rope 31 hooked onto the lifting section 74 automatically slides along the arc of the lifting section 74 to the middle of the lifting section 74, so that the upper and lower ends of the lower lifting rope 31 are aligned and the lower lifting rope 31 is in a vertical state.

[0032] The drainage cylinder lifting device described in this embodiment uses the cross-shaped lifting bracket 1 and the lower lifting lug 3 to unfold the lower lifting rope 31. The lower lifting rope 31 can be vertically connected to the lifting section 74, ensuring that the lower lifting rope 31 does not contact the outer wall of the drainage cylinder 01 during lifting, and will not scrape the concrete structure and cause it to collapse. At the same time, the pre-embedded lifting pin shaft 7 is pre-installed and is not retrieved as part of the drainage cylinder 01. The lower lifting rope 31 can be hooked onto the lifting section 74 of the pre-embedded lifting pin shaft 7. After the drainage cylinder 01 is lifted into place, the diver can directly remove the lower lifting rope 31 from the lifting section 74 and only retrieve the lower lifting rope 31. The lower lifting rope 31 and the lifting section 74 can be quickly disconnected, reducing the difficulty of underwater operations. This drainage cylinder lifting device has a simple structure, is easy to use, and has good performance.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
